What are the precautions for cedar maintenance?
This article explains the precautions for cedar maintenance and the cultivation management points of growing cedars, which are very useful gardening tips worth collecting!
Cedars belong to the Pinaceae family and the Cedrus genus. The cedar species in China is the Himalayan cedar. Due to its tall and upright form and strong ornamental value, people often cultivate it as an ornamental plant in gardens; in addition, cedars also have high commercial and medicinal values. Let's introduce the methods for growing cedars next.
1. Temperature
Cedars prefer warmth, and the optimal environmental temperature for their growth is 20-25 degrees. However, as an evergreen forest tree growing in temperate regions, cedars have strong cold resistance and do not require special insulation measures in winter. But if it is a potted cedar, moving it indoors during low winter temperatures is beneficial for its growth.
2. Watering
Cedars do not have high water requirements, and it is sufficient to keep the soil slightly moist during the growth process. The growing period is when cedars grow fastest and most vigorously, and the watering amount and frequency for cedars should be increased at this time. Be sure not to overwater to avoid waterlogging and root rot.
3. Fertilizing
Cedars do not have high fertilizer requirements. To prevent insufficient nutrient supply during the growing period, which could slow down growth, fertilizers such as decomposed fertilizer cakes can be applied. The fertilizing frequency is twice to three times a year, with the principle of applying thin fertilizer frequently. Fertilizers should be diluted before application to avoid root burn.
4. Soil
Cedars are suitable for growing in acidic soils with deep soil layers, loose and breathable, and good drainage. If the soil is too compact and easily compacted, it can lead to poor root respiration, which is not conducive to the healthy growth of cedars.
5. Light
Cedars enjoy light and need plenty of sunlight for photosynthesis. However, cedars cannot tolerate strong direct sunlight, and proper shading is required when sunlight is intense. It is best to place them in a gentle diffused light environment.
6. Diseases and Pests
The main diseases and pests of cedars are gray mold. If gray mold is detected on cedars, they should be moved to a well-ventilated environment, overly lush branches should be pruned, and diseased branches should be cut off promptly to prevent infection of healthy branches. During the outbreak, a 65% wettable powder of zinc omethoate 500 times solution or a 45% wettable powder of ammonium omethoate 1000 times solution can be sprayed for treatment.
7. Propagation
Cedars are generally propagated by播种 (seeding) and cutting. Seeding can be done in late March, with seeds soaked for 1-2 days before播种. Cuttings are usually done in spring and autumn, with the cuttings soaked in disinfectant before planting, and strict shading after planting.
